General and Desktop

Hi and welcome to devnet, Do you mean something like described in the Qt Test module documentation ?

@StudentScripter For the grouping you have to use an adequate data structure. As for hovering, IIRC, you have to have mouse tracking enabled on the view.

Hi, If you want to do styled painting you should rather use the QStyledItemDelegate as a base. Next, how do you expect the default QStyle to make use of your custom options ? It knows nothing about them. Depending on what you want to achieve you should write a proxy style that make use of your custom options.

Hi and welcome to devnet, You need to wait for the media to be loaded before requesting metadata. I haven't tested it but the metadataChanged signal might indicated that they are now available.

@wasawi2 Start by placing some breakpoints/debug messages e.g. in your resizeEvent()? Check the value of size(). Not sure why you have to do this resize in code, but maybe. Your LineWidget instance(s) themselves have a layout onto which the chart view is placed?

@Pl45m4 Calling slots as a normal function directly from main thread, reading/writing from/to a variable of QObject (using mutex of course).

@JacobNovitsky Qt Creator is an IDE, for editing and building from source code. There is no "add and manage threads in Qt Creator". See https://doc.qt.io/qt-6/thread-basics.html and https://doc.qt.io/qt-6/examples-threadandconcurrent.html for using threading in a Qt application. And please make sure you really need threading in your Qt application, which already works asynchronously for many things. A large proportion of beginners who think they need threads in a Qt program turn out not to need them and would be better off without.....

@sierdzio This is $PATH I set [image: a3b4c34e-8d02-4209-b93e-5153ea8dfeb0.png] I ran CMake command like this: cmake -DCMAKE_PREFIX_PATH=/home/Qt/6.5.2/gcc_64 -DQT_DIR=/home/Qt/6.5.2/gcc_64/lib/cmake/Qt6 -DCMAKE_BUILD_TYPE=Release ..

it turns out this bug also can be reproduced in two dispalys with same DPI settings.

@fstech_12 It looks like another instance of the installer is running. You can check in Task Manager and kill it there. If you still get this error then delete the file mentioned in the error message manually and try again. And finally (typical Windows workaround): reboot your machine :-)

@booter Do you have a question? If you get this error - did you install the packages mentioned in this thread?
